fix: formatDistance for Basque (eu)

[eillarra]

As a reference you can take a look at moment.js, which was updated years ago by me: https://github.com/moment/moment/blob/develop/locale/eu.js

For example, "en {result}" was still in Spanish...

I don't speak the language, but the changes look good to me!

@eillarra can you confirm that there are no unintended behavior changes in the updated snapshot? d97aa76

@fturmel snapshot looks good. There is only one thing that it is not perfect, but I don't think it is possible with the current implementation:

6 urte gutxi gorabehera barru should be 6 urte barru gutxi gorabehera

But suffix is added after result is calculated, and the 'about' (gutxi gorabehera) is added beforehand to the result, so I guess it needs to stay like this. Thanks!

Keep this on hold for a moment... I only checked formatDistance, but I will check the other files too so the revision is complete. There might be a couple of small extra issues that can be solved.

Great! Here's the unicode CLDR reference if needed: https://www.unicode.org/cldr/charts/44/summary/eu.html

If you change anything else, you can update the snapshot markdown file yourself by running npm run locale-snapshots.

I'm sure it's possible to reshape the formatDistance function to support the "about" form you're describing. How does this look?

if (options?.addSuffix) {
  if (options.comparison && options.comparison > 0) {
    if (token.startsWith("about")) {
      return result.replace("gutxi", "barru gutxi");
    }
    return result + " barru";
  } else {
    return "duela " + result;
  }
}
